I can't find friends on OSM and they can't find me either... what could be the reason for that bug? I have tried to add them with the correct username and it just didn't find them. So they tried it with my username on their account and they didn't found me either.. How can I fix this?
Thank you.

@mugamishai Hi, welcome.
There's a simple explaination for that, then you're playing on two different versions of the game.
In this case you're playing on world version, so you're friend are playing on the Dutch version of the game.

If you want to add them as friends, play together etc, then you all should play the same version of the game.
